WALTER H. oonns, for 'rnoY, OHIO.

OVERHEAD IRRIGATING DEVICE.

of the city of il roy, in the county of Miamiand State of Ohio, have invented certain new and useful Improvements in Uverhead lrrigating Devices,of which the following is a full, clear, and exact description, reference being had to the drawings accompanyin this specification. 1

11y invention relates to irrigating systems wherein a series of parallel pipes are mounted transversely of a field, and a series of line nozzles securedin the PlPQS/fOI' sprinkling the field with a fine spray of water. It applies more particularly. to such devices where the transverse parallel pipes are rotatable axially thereby permitting a complete and even distribution of water over the desired surface. r

It is the particular object of this invention to provide a new and useful endor terminal nozzle for an irrigatingsystem of the above character. The difliculty with any system'of complete water distribution from overhead is that the wind must be allowed for, since the result of a breeze blowing lengthwise of the pipes would be to deprive the windward side of any field to be sprinkled, of any water. or

. According to my invention, therefore, I provide, in combination with long revoluble pipes having spray nozzles distributed throughout their length, for terminal spray nozzles having independent valves,directed so as to throw the spray outside the area to be covered. 7

My object and its attendant advantages 1 accomplish by that certain construction and arrangement of parts to be hereinafter more specifically pointed out and claimed.

In the drawings,

Figure 1 is a perspective view showing a single revoluble sprinkling line.

Fig. 2 is a diagrammatic view showing the area covered by a sprinkling line under the influence of the wind.

Fig. 3 is a detailv elevation showingv the new terminal sprinkling nozzle and faucet. Fig. d is a deta1l elevationof modified form of end nozzle.

Specification of Letters Patent.

Patented July 5, 1921.

Application filed July 2, 1919. Serial No. 308,085.

of any desired form of standards 1 extending across a field upon which is revolubly mounted a sprinkling pipe 2 which has a series of spray nozzles 3 of any desired type, but adapted to throw a very minute jet of water. These nozzles are spaced equidistant from each other, this distance being calculated so that the water is evenly and uniformly distributed over the surface ofthe field to be irrigated. The handle l is shown asindicatlng some method of revolving the .pipe 2. as will be readily understood.

There may be any desired number of sprinkling lines dlstributed across the field tobe'irrigated, and revolved by some sort of mechanisms simultaneously in order to evenly and uniformly sprinkle the desired area.

In the past, the spacing of the nozzles and the speedof revolution thereof have been WOlkBCl'Wltll great particularity but I have noted, as has been above set forth, that a cross wind when blowing along the length of the sprinkling lines -will disturb this ElSfglbHtlOn along the windward side of the Accordingly I provide a special nozzle at one or both ends of the sprinkling lines which is directed so asto throw the jet outside of the field when the air is still.

As an example of such a device, I show in Fig. 3 a small bib or faucet 5 screwed into the'pip'e 2 with the valve therein controlled by the handle 6. Mounted suitablv in the spout portion 7 of the bib is one of my spray nozzles 8, (such for example, as I shoir in my Patent No.- 1,126,707, dated Februarv 2, 1915. l

It will be noted that the nozzle 8 extends at a considerable angle to the regular nozzles 3, the exact angle being dependent upon which end of the pipe this special nozzle is located and upon the usual factors of water pressure and area to be covered.

As shownin Fig. 2, a wind blowing in the direction of the arrows will deflect all of the jets, 2 from the regular spray nozzles so that a space is left near the end of the pipe which receives no water. Under such circumstances the angled nozzle 8 is turned on and the nozzle, 8*, at the other end of the sprinkling line turned off. The wind will then deflect the jet 8 from the nozzle 3 in such a way as to cause it to cover with water the space which the usual nozzles cannot reach, due to the wind.

The particularfeature of the nozzle resides in the fact that it is turned at an angle to the radius of the pipe of the sprinkling line, and that it is possible to turn it OE, and on, independent of the normal water supply of the rest of the pipe. The nozzle should, however, be of an eflicient type, such as my patented nozzle abovereferred to, because a mere make-shift would not give that fine distribution of water which is necessary for proper overhead irrigation.

In lieu of the single nozzle, I may also provide aplurality of jets to prevent the over-accumulation of the spray into large sprinkling-a fixed area regardless of wind variations, the combinatlon of a sprinkling element adapted to spray a plurality of fine jets ofwater parallel to each other for covering such area in the absence of wind defiection, and a sprinkling element adapted to normally direct its spray outside of the area desired to be covered, at an angle to normaljets and'on'a line calculated to bring the spray from said' element within said area angles, adapted to direct its spray at diverupon wind deflection. V

' 2. An overhead irrigating system comprising a sprinkling. pipe located within an area desired to besprinkled, having distributed nozzles through its length for throwing fine sprays of water parallel toeachother on a perpendicular plane to the pipe forcovering said area, of terminal nozzles for such pipe adapted to direct sprays at divergent angles to the remalning nozzlesand outside of the area desired to be covered, said nozzles hav-l ing {means for cutt ng off the water there-i from independent from the remaining noz zles in said pipe, and said angular direction of the terminal nozzles beingcalculated for normal wind deflection to bring their spray within the desired area. 1 1

'3. In an overhead irrigating system, the combination with a. revoluble sprinkling pipe, having spray nozzles distributed equidistantly along itslength for throwing fine jets of water parallel to each other, and spaced so as to evenly cover the entire area traversed by the pipe with an equal amount of water, of a terminal nozzle for such pipe, adapted to direct its sprayat a divergent angle to the remaining nozzles and outside of the area desired-to be covered, but calcu lated to be overcome by the wind, said nozzle having means for cutting off the water therefrom independent from the remaining nozzles in said pipe, whereby said terminal nozzle can be employed to'sprinkle that portion of the windward side ofthe area which would otherwise be deprived ofwater by de:

'fiecting action of thewind on the spray from gent angles tothe remainingnozzles and outside of the area desired to be covered, butcalculated to be overcome by thewind, said nozzle having means for cutting off the water therefrom independent from the re maining nozzles in said pipeywhereby said terminal nozzle can be employed .to sprinkle i that portion of the windwardside'of thearea which would otherwise be deprived of water by deflecting action" of thewind on the spray from the remaining nozzles.
